(FORTUNE Magazine) – Re ''Who's Ahead in the '88 Money Race'' (June 8): I understand that former Congressman Ron Paul, who is running for the Libertarian party presidential nomination, has raised close to $200,000, more than many of the people on your list. Yet you did not mention Mr. Paul. I fail to understand how the democratic process is supposed to work when one of the parties on the ballot is not allowed the right to be heard. L. A.
